📦 Installation

Choose Your Instrumentor Type:

HoneyHive supports both OpenInference (lightweight) and OpenLLMetry (enhanced metrics) instrumentors.

Option A: OpenInference (Recommended for Beginners)

# Install with OpenAI integration (most common)
pip install honeyhive[openinference-openai]

# Install with Anthropic integration
pip install honeyhive[openinference-anthropic]

# Install with Google AI integration
pip install honeyhive[openinference-google-ai]

# Install with multiple providers
pip install honeyhive[openinference-openai,openinference-anthropic,openinference-google-ai]

# Install all OpenInference integrations
pip install honeyhive[all-openinference]

Option B: OpenLLMetry (Enhanced Metrics)

# Install with OpenAI integration (enhanced metrics)
pip install honeyhive[traceloop-openai]

# Install with Anthropic integration
pip install honeyhive[traceloop-anthropic]

# Install with Google AI integration
pip install honeyhive[traceloop-google-ai]

# Install with multiple providers
pip install honeyhive[traceloop-openai,traceloop-anthropic,traceloop-google-ai]

# Install all OpenLLMetry integrations
pip install honeyhive[all-traceloop]

Option C: Mix Both Types

# Strategic mixing based on your needs
pip install honeyhive[traceloop-openai,openinference-anthropic]

Basic Installation (manual instrumentor setup required):

pip install honeyhive

📋 Including in Your Project

For detailed guidance on including HoneyHive in your pyproject.toml, see our pyproject.toml Integration Guide.

🔧 Quick Start

Basic Usage

from honeyhive import HoneyHiveTracer, trace

# Initialize tracer
tracer = HoneyHiveTracer.init(
    api_key="your-api-key",
    source="production"
)

# Use unified decorator for automatic tracing (works with both sync and async)
@trace(event_type="demo", event_name="my_function")
def my_function():
    return "Hello, World!"

@trace(event_type="demo", event_name="my_async_function")
async def my_async_function():
    await asyncio.sleep(0.1)
    return "Hello, Async World!"

# Manual span management
with tracer.start_span("custom-operation"):
    # Your code here
    pass

# With HTTP tracing enabled (new simplified API)
tracer = HoneyHiveTracer.init(
    api_key="your-api-key",
    source="production",
    disable_http_tracing=False  # project derived from API key
)

Initialization

The HoneyHiveTracer.init() method is the recommended way to initialize the tracer:

from honeyhive import HoneyHiveTracer

# Standard initialization
tracer = HoneyHiveTracer.init(
    api_key="your-api-key",
    source="production"  # project derived from API key
)

# With custom server URL for self-hosted deployments
tracer = HoneyHiveTracer.init(
    api_key="your-api-key",
    source="production",
    server_url="https://custom-server.com"  # project derived from API key
)

Enhanced Features Available

from honeyhive import HoneyHiveTracer
from openinference.instrumentation.openai import OpenAIInstrumentor

# All features are available in the init method
tracer = HoneyHiveTracer.init(
    api_key="your-api-key",
    source="production",
    test_mode=True,  # Test mode support
    instrumentors=[OpenAIInstrumentor()],  # Auto-integration
    disable_http_tracing=True  # Performance control
)

✅ The init method now supports ALL constructor features!

OpenInference Integration

from honeyhive import HoneyHiveTracer
from openinference.instrumentation.openai import OpenAIInstrumentor

# Initialize tracer with OpenInference instrumentor (recommended pattern)
tracer = HoneyHiveTracer.init(
    api_key="your-api-key",
    source="production",
    instrumentors=[OpenAIInstrumentor()]  # Auto-integration
)

# OpenInference automatically traces OpenAI calls
import openai
response = openai.ChatCompletion.create(
    model="gpt-3.5-turbo",
    messages=[{"role": "user", "content": "Hello!"}]
)

Enriching Spans and Sessions

v1.0+ Recommended Pattern: Instance Methods

from honeyhive import HoneyHiveTracer

# Initialize tracer
tracer = HoneyHiveTracer.init(
    api_key="your-api-key",
)

# Use instance methods for enrichment (PRIMARY - Recommended)
@tracer.trace(event_type="tool")
def my_function(input_data):
    result = process_data(input_data)

    # ✅ Instance method (PRIMARY pattern in v1.0+)
    tracer.enrich_span(
        metadata={"input": input_data, "result": result},
        metrics={"processing_time_ms": 150}
    )

    return result

# Enrich session with user properties
tracer.enrich_session(
    user_properties={"user_id": "user-123", "plan": "premium"}
)

Legacy Pattern: Free Functions (Backward Compatibility)

For backward compatibility, the free function pattern from v0.2.x still works:

from honeyhive import trace, enrich_span, enrich_session

# Free functions with automatic tracer discovery (LEGACY)
@trace(event_type="tool")
def my_function(input_data):
    result = process_data(input_data)

    # Free function with auto-discovery (backward compatible)
    enrich_span(
        metadata={"input": input_data, "result": result},
        metrics={"processing_time_ms": 150}
    )

    return result

# Enrich session via free function
enrich_session(user_properties={"user_id": "user-123"})

⚠️ Deprecation Notice: Free functions will be deprecated in v2.0. We recommend migrating to instance methods for new code.

Why Instance Methods?

• ✅ Explicit tracer reference (no auto-discovery overhead)
• ✅ Better multi-instance support (multiple tracers in same process)
• ✅ Clearer code (explicit is better than implicit)
• ✅ Future-proof (primary pattern going forward)

Key Design Principles

1. Singleton Pattern - Single tracer instance per application
2. Environment Configuration - Flexible configuration via environment variables
3. Graceful Degradation - Fallback mechanisms for missing dependencies
4. Test Isolation - Comprehensive test suite with proper isolation
5. OpenTelemetry Compliance - Full OTEL standard compliance
